Little late reply but we got 8 GTX580 cards working in Tyan running Windows 7 but we have the older FT72. I can always check our BIOS settings.

BIOS is set to 64-bit resources, onboard VGA disabled, VT disabled, VT-d disabled, MMIOH size set to 128G, everything else I could find disabled as well, but I can't get the 8th GPU to work - Windows reports code 43 on the 3rd card in device manager. The card is fine - if I disable another card (for example, #4), then disable and re-enable #3, it comes up fine, but if I subsequently re-enable #4, then it reports error 43. Basically, whichever card comes up 8th in a system with seven cards, fails to do so. Tried different versions of NVidia driver, but that didn't help either. I know people are running these systems with eight cards... what's the secret sauce?
